CABLE-ADJUSTING DEVICE Fen STEERING QUADRANTS.

Application filed May 19,

This invention relates to :1 marine steering quadrant,and more particularly to that elnss i \i'here incens is provided to nd1ust the lengtn oi the steering cables which have their ends attached thereto.

lot is new the generiil pmrtiee in the instnllotion of steering gears on vessels to attach or mount a quadrant upon the upper end oi: the rudder post, and from this quadrant to run the steer .ng c: bles through proper guide blocks or pullveysto a drum ottneherhto the st 'ing post; the endsot' said cables being secreted to said q uulrnnt by threading the ends through holes in line with the grooves in the peri ihcry oi the quadrant and either terinin g at huot thereinor placing zichimp thereon to prevent the withdrawal of the cehle through the holes; and to make any adjustment in the length of thecohles caused by stretch, turnbuckle is placed in the cables; near the quadmm, which not easily gottenet as the quadrent is mounted under the decking in a small space, and can not he readily gotten at.

The ohject of the present l11'VO11l).1()T1, 1S li() provii'ic either a steering quadrantembodying an ndjustehle clamping means for the steering C'tllilto, or such an adjustable clamping means that may be attached to steering quz1droots which are now iiruse; thus providing them with the hike-up lez 'ture.

Another oh iect of the invention is to proride on :uljustnble teke up mhle clump, that shell be simple, contein m ports, nliord at positive grip tor thccnd ol': the cable, and be easily adjusted in :1 small space and without the use of special "tools. 7 Still. :1 further ohject heing to provide a cable hike-up menus that can he attached to the arms of e steering quadrant, irrespective of the shape or form of cross section of sold ZM'UIS or spokes.

A further object of the invention is that it sin gle cable may he employed on each side of thebont, lending from the steering gear to the quadrant, and, no splices or turnhlichles are required: end also that the cable may he re newed without splicing, and as the device is tubular, the eahle may he threaded there throi'lgh and the sleek taken up before the same is elmnped.

With these and other objects in iew, my invention conslsts in certain novel construction and ctnnltxinstion of parts as will herein after he described and claimed, and 111115- triued in the aecompmiymg drawings, 111

which like liguresof reference refer to corresponding parts in allofthe views, but itis understood that slight changes may he made w rithout departing from the spirit'of the invention. 1 I

in the d rowing:

Figure 1 shows the upperside of a quadrant with the cable tnke-up means attached. thereto.

Figure 2 shows an enlarged view of one of the spokes, illustrating the method of attaching the cable take-up tothe spoke of the quildronta Figure 3 shows the szune. Figure SE is n cross sectional yiewof the Sl'mlflfflllfl cnhle takemp (lev.iee,tnke11 on the line AA ot FigureB.

Figure 5 iso cross tionnlview of the same, taken on the line 13 B of Figured l igure 6 shows a inodified form of the device, inivhich the adjustingineans is attached to the center spoke. i i

Figure 7 is it sectional View of the saline takenon the line C-Cof Figure 6.

Referringto thedrawingr-- r The usual lorm of steering quadrantisindicoted, and comprises the hub 10, provided with the cap 11, held in place by the bolts 12; and radiating therefrom are the spokes 13, which are hereshownes Tsh'aped in cross section, but which may be of any desired shape and tothe outer ends thcreofis formed at rim or sector 14, which is provided with the flanges 15,1?o'r thesteering cables 16. i 1 The cable take-up oradjusting ineans, C0111- legs or cars 18, projecting from the sides a partial enlarged viewof thereof, and formed withholes (for the 1'e ception of the ends of the U-holts 19, which i emhrace the spoke 13, and secure the plate 17 tosaid spokelfl by thenuts 20; While the wooden tiller blocks 21 are provided as shown in Figure the shape of these filler blocks being determined by the fOllIl of the spoke; that is. it a round spoke was used, the blocks 21 would have to he concave tofitthe same.

The outer end of the plate 17 is n'i'ivided with n rounded )OlhlOl] 22. to )rovidc an ens turn for the cable 16, as said cable must not only be properly supported for-the right angle bend required, but must be capable of being easily drawn tondjust its length.

Near the other-end of said plate 17 ,there is torrned or otherwise attached a leg 23, 'Wltml'i is formed with holefleywhieh 1s elem mounted within said lug 23, and which is provided with the external threads 26, upon which are threaded the wing nut 27 and the locking nut 28.

The other end of said tubular member 25, is reduced in diameter at 29; slotted at 30 to 7 form a collet, and provided wit-h the taper threads 31 and a taper nut 32 the object being to pass the end of the steering cable 16 through the same; secure the cableto the member 25 by said collet, and adjust the position of the same with regard to the lug 23 and plate 17 by the nuts 27 and 28.

lVhile this form of cable securing means is here shown, it is to be understood, that any suitable means may be employed for securing the end of the cable to the adjusting device, such as a turnbuckle.

I It will be noted that the groove in the rim of the quadrant and the groove in the block or rounded portion 22, and the hole in the lug. 23 are the width of two cables; this being necessary for the reason that the cables runin opposite directions and must freely pass each other; thus one cable is above the other, and the adjusting member 25 for one cable will. be to one side of the hole 24, and for the other cable will be to the opposite side of said hole 24:, thus alining with the cables.

It is also to be noted, that while the device is here shown in the form of an attachment, which may be secured to any of the usual types of marine steering quadrants, that in many cases, it will be found to advantage, to form the rounded portion 22 and the lug 23 integral With the spoke 13 of the quadrant.

Referring to the modified construction illustrated in Figures 6 and 7, the plate 17, i in place of being secured to the outer side of one of the side spokes 13, is secured on the face of the center spoke 18, by the U-bolts 19 and nuts 20; said plate 1'7 being formed with. the rounded portions 22, but said portions 22 are curved as shown in Figure 7, to allow the cable 16 to be brought upward to the level of the device as shown.

Havingthus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In. a cable adjusting means for a steering quadrant, and in combination with a steering cable, of an adjusting means comprising a cable guide and a-lug adapted to be secured to said quadrant, clamping means adapted to secure said cable, and means for adjustably securing said cable clan'iping means to said lug for the purpose of adjusting the length of the cable.

2. In a cable adjusting means for a steering quadrant, and in combination with the steering cable, of a plate adapted to be sccured to the quadrant in a rigid manner, a cable guide formed on one end of said plate for guiding the bend of said cable, a lug formed on said plate, a tubular member slidably mounted in said lug, a cable gripping member secured to said cable and to said tubular member, and means for adjusting said tubular member within said lug for the purpose of varying the length of said cable.

3. A cable adjusting device for quadrants, comprising in combination with a cable, of a clamping member secured to said cz .ble, and adjustlng device secured to said quadrant and means for adj ustably securing said clamping member to said adjusting device, comprising a threaded member, a lug formed on said adjusting device and adapted to receive said threaded member, and nuts threaded thereon and in contact with said lug, for adjusting and locking said threaded member with respect to said lug.

In testimony whereof I afiix my signature.
